ACCESSORIES, ANCILLARY EQUIPMENT, AND CONTROLS
CYCLING OR VFD-CONTROLLED REFRIGERATED AIR DRYERS Requirements: • New dryers must be properly sized to meet the needs of the compressed air system. • New dryers must be cycling or variable frequency drive (VFD)-controlled refrigerated dryers replacing non-cycling refrigerated dryers. The replacement of desiccant, deliquescent, heat-of-compression, membrane, or other types of dryers are not eligible. • If air dryer is integral to another piece of equipment (i.e., is part of the air compressor), provide a manufacturer’s specification sheet for that piece of
equipment to confirm that it includes a cycling or VFD controlled air dryer. • Installation of controls to existing dryers does not qualify for an incentive. • For new construction, cycling or VFD-controlled refrigerated dryers must be installed instead of non-cycling refrigerated dryers. • Controls-based efficiency projects and/or the replacement of other dryer types may qualify for a custom incentive.

DEWPOINT DEMAND CONTROLS FOR DESICCANT DRYERS Requirements: • Complete Table C of the “Process Systems Incentive Catalog Supplemental Data Sheet” for this measure. • For “Hours of Operation,” enter the total hours per year the compressed air system operates. • For “Air Compressor Type,” enter “single-acting reciprocating,” “double-acting reciprocating,” “single stage rotary screw,” “two-stage rotary screw,” “oil- free rotary screw,” “centrifugal,” or “other.” • For “Air Compressor Control Type,” enter “Variable Speed Drive,” “Load/Unload,” “Inlet Modulating Damper,” or “Variable Displacement.” • For “Desiccant Dryer Type,” enter “Heatless,” “Heated,” or “Blower Purge.” • Dryer controls are only for use on heatless, heated, or blower purge desiccant dryers. • Dryer must have a dew point sensor at discharge to monitor demand. • Dryer controls must control the regeneration process based on actual dewpoint instead of regenerating based on time alone.
• Dryer controls are not eligible for backup/redundant desiccant dryers. • Use the CFM value of the dryer when calculating the incentive amount. EQUIPMENT UPGRADES AND RETROFITS Measure Description
